A lot of tutorials online teaching how to port the Siri GUI over with no functionality. I do have access to an iPhone 4S, so I am wondering if i can follow those tutorials but modify some system files on my iPhone 4 to bluff Apple's server with the UDID of the 4S that I have access to?

The 4S in question actually belongs to my girlfriend, so I believe the combined usage from the both of us shouldn't be so high as to alert Apple of unusual traffic I assume? She rarely uses her Siri anyways.
